Using Lithium-ion battery offers many advantages over older SLA (Sealed Lead Acid) battery because of Lithium-ion battery's high energy density, small size, and low weight. A typical Lithium-ion battery may only has 1/4 of weight and 1/2of size compare to same capacity traditional heavy bulky Sealed Lead Acid batter. This battery weight is only around 4 pounds. A same capacity Sealed Lead Acid battery may weigh around 20 pounds.)

Battery Type

Lithium ion Battery

Lead Acid Battery

Voltage fluctuation in working

Remains stable with different output

Voltage fluctuation based on output

Cycle life
(Residual capacity over 5%)

500 ~700 cycles

150~300 times

Capacity

Very stable and very little affection by output current

Suffer a big affection in by output current. Capacity will be much smaller than rated capacity when output current is large.

Depth Of Discharge (D.O.D.)

99%

50% ~ 60%

Self discharge rate (per month)

1~1.5% (Capacity remains over 80% even the battery is idled for one year)

30% (Battery capacity drops near to zero if it is unused for 3 months)

Fast charge capability

Charge to full capacity in about 6 hours

It needs 8 ~ 12 hours to fully charge the battery

Discharge working temperature ℃

-20～+75

-20～+55

Memory effective

None

None

Thermal stability

Outstanding

Acceptable

Weight (Compare to the same capacity)

1/4 of weight to lead acid battery

comparatively heavier weight

Installation

Any direction

Upright position is necessary

Safety

with built-in safety protection function

Dangerous of acid leakage

Environmental conform-ability

Conforms to RoHs standard

Violet RoHs standard；Lead and sulphate acid are pollutant

Disposition of used battery

Lithium-ion batteries are
generally not considered an environmental hazard because they do not
contain lithium metal. The United States government labels them as
non-hazardous waste and does not oppose them being discarded together
with the trash that makes up the local waste stream.

Needs special recycle, after treatment utility

Charging the Battery:

The battery can be recharged by the provided AC charger from 100V ~ 240V AC power source.

KF562 Holder & Output Box can be used as a battery holder and mount on the frame vertically or horizontally. The battery then can slide on /off to the output box and locked with key. It is designed for multi -direction installation. User can change the position of battery (vertically / horizontally) by adjusting the clamp.

Flat Output Box

If you do not need to mount the battery to anywhere, you may also select Flat Output Box to same some space. It looks like this:

The 15A fuse, serves as a second protection device, can prevent the battery pack from excessive discharge.

It is easy to hold the battery with the well designed handlebar.

Battery can be recharged either by fastening on the bike or by itself with the provided AC adapter.

The LED (at the power button controls on/off of the battery) glows when power is on.

The key lock is used to fix the battery onto the holder.

Battery holder can be welded on the bike vertically or horizontally. The Contact of KF541 is also adjustable in order to enhance the flexibility of battery installation.

KF542, the fixed holder, is designed for multi-direction installation. User can change the position of battery (vertically / horizontally) by adjusting the clamp.

Battery can be installed easily. Simply slide the battery towards the holder by following the track.
